Initializing a 2 dimensional array of a class in another

I have a class say ABC and I have to initialize a 2 dimensional array of type ABC into another class. I am bad at objective C. Tried lots of ways, but facing some errors.

Here is ----- Class ABC ------

@interface ABC : NSObject{
int a;
}
@property (nonatomic, assign) int a;

@end

@implementation ABC

@synthesize a;

@end

Here is another class say XYZ where class ABC needs to be intialized:

------ Class XYZ -----

@interface XYZ : UIView {

ABC *abc[16][16];
}
@property (nonatomic, retain) ABC *abc;
@end

@implementation XYZ
@synthesize *abc[16][16];
@end

Please suggest what could be the correct syntax of initialization. I am getting various errors everytime I 开发者_JAVA技巧try to initialize it.

If you want to use C style arrays (i.e. ABC *abc[16][16]), you’ll need to provide accessor methods in your XYZ class.

@class ABC;

@interface XYZ : NSObject
{
   ABC *abc[16][16];
}
- (void)setABC:(ABC *)anABC atRow:(NSUInteger)row column:(NSUInteger)column;
- (ABC *)abcAtRow:(NSUInteger)row column:(NSUInteger)column;
@end

@implementation XYZ

- (void)setABC:(ABC *)anABC atRow:(NSUInteger)row column:(NSUInteger)column
{
   [anABC retain];
   [abc[row][column] release];
   abc[row][column] = anABC;
}

- (ABC *)abcAtRow:(NSUInteger)row column:(NSUInteger)column
{
   return abc[row][column];
}

- (void)dealloc
{
   NSUInteger row, column;
   for (row = 0; row < 16; row++)
      for (column = 0; column < 16; column++)
         [self setABC:nil atRow:row column:column];

   [super dealloc];
}

@end

You can't use [] type arrays with properties as in XYZ - what you can do would be to create an NSArray or similar container and create the multidimensional array in that way
